TavliGal - 05 Mar 2004 06:49 GMT
Hi all,
I've been doing pretty good, not too many cravings (I'd say any cravings I
have had are due to emotional triggers rather than physical) but at the same
time, I'm wondering if I restrict my calories too much to soon, am I going
to screw my metabolism?  For example at my weight and activity level I burn
an estimated 3,400 calories/day, and I'm eating approximately 1700
calories/day.  I shoot for at least 2200/day but, as is typical with this
WOE,  I just havent been too hungry lately, (it's the good time of the month
right now) in another week and half my appetite will increase again.
While I'd love to lose as much weight as quickly as possible, I don't want
to slow down my metabolism too much and if I keep it to 2lbs per week then I
should be eating approx. 2500 calories /day.  My concern is, should I be
trying to go for higher calories? When I finally hit maintenance I don't
want to have slowed down to a point where my metabolism can only handle 1200
cals a day, know what I mean?
Any comments/suggestions?
Thanks, Monica

Oh, at 3400, what exactly is your activity? This is a lot...

Well I carry about 334lbs all day and my estimate is based on light to
seated activity.  Not exercising a whole lot right now, but I am moving more
than I used to.

I believe that you have misscomputed this...

try this...

http://www.exrx.net/Calculators/CalRequire.html

I think your calorie requirements are about 2300 cal/day now. 1700 for
losing is very reasonable.

Do not be afraid about starvation mode until you are below 1000 cal/day.

I agree. Also, what exactly is your current rate of loss and how much have
you been eating? Without that information what you've posting is
meaningless.

Hi there,
I did the calculations on that site and it pretty much corresponds to my
fitday calcs too, I have the PC version.
I calculated it at:  7 hrs rest ( I rarely sleep more than that) 13 hrs at
very light, and 4 hours at light =
2208 BMR (is that resting metabolic rate?)
1150 Activity Calories
3,358 Total Calories
I'm 5'2.5"

On a more conservative calulation of only very light activity at 17hrs and
7hrs sleep, the BMR stays the same and the activity calories go down to 782
which = 2990 Total Calories.
Therefore I burn at least 2990 - 3358 calories/day.  Since Jan 20th, as of
this morning, I've lost 28.6lbs
The overall rate of loss per week has been 4.45lbs/week.
The overall rate of loss per week over the last 14 days = 3.23lbs/week.
I'm averaging approx 28% protein, 62% fat, and 11% carbs with an overall
average of 2024 calories a day.
There are many days where I'm at a max of 1700 cals which is why I was
wondering if that would hurt in the long run.

I don't think this calculator can be very accurate...it said I should be
eating over 2300 calories, and I have never eaten that many unless it was a
special occasion.  I try to stay less than 1500.

I assume the 2300 number is the "total calories" the calculator comes up
with by combining basal and activity calories.  If you are just looking
at the total and not adjusting downward for weight loss, remember that
"2300 total" is your *maintenence level* for your *current weight*.  To
lose a pound a week at your current weight, you need to eat 500 calories
less (2300-500=1800)-- since you say you are trying to stay under 1500
(how much under?), your loss should be between 1.5 and 2 pounds a week
(depending on how often your calorie level comes to 1300 a day, and
still assuming the 2300 is your basal+activity with no other modifiers).
Does this sound about right to you?

If you've already done the math and the 2300 is your
bmr+activity-calorie restriction for weight loss then you are beyond the
parameters of the Harris-Benedict calculator --athletes and the *very*
overweight do not get accurate estimates with this formula (the most
common calculator on the web).

If you know your lean body mass, then you can use the Katch-McArdle
formula to get the most accurate BMR estimate available.  This formula
takes into account lean body mass and is therefore more accurate than
the Harris- Benedict formula which is based on total body weight.  By
the way, the Harris-Benedict formula uses different formulas for men and
women because men generally have a higher LBM and this is factored into
the men's formula.  Since the Katch-McArdle formula accounts for LBM,
this single formula applies equally to both men and women.

BMR (men/women) = 370 + (21.6 X lean body mass in kg)
OR
BMR (men/women) = 370 + (9.8 X lean body mass in lbs)

a quick way to find your lean body mass
http://www.intmed.mcw.edu/clincalc/body.html.

But you still have to remember that the answer to this calculation will
also be a maintenence level of calories for your current weight.  I
don't know of a calculator that does the  subtraction for weight loss
for you (although it would be THE killer app for dieters.  Any
programmers want to tackle creating a lean body mass calc combined with
the Katch-McArdle AND auto subtraction of 500 and 1000 cals for the two
major weight groups -- those with 50 or less pounds to lose, and those
with 100 or more pounds to lose that displays one "calories to shoot
for" answer depending on whether the user indicates which group he/she
is in?)

I could probably do it - my question would be, do you want something that's
PC-resident and can keep track of things, or just a web-based calc that
doesn't track?  My programming skills are lying fallow these days and
getting rustier all the time, but I could probably come up with something
workable for PC.  For a web-based one I probably wouldn't have time to
tackle it - I haven't done that much scripting anyway, and so I'd have to
delve back into the books for awhile before I could even start, <g>.

Hey PC-resident with tracking sounds fab!  If it takes off like hotcakes
would you be wanting to market it or would it be a gift to asdlc?  Hmm
perhaps some built-in non killable without a lot of work announcement of

Nah, it'd be a gift.  Selling it means I'd be obligated to support and
update it constantly, <g>.  I'd need someone else to host it for downloading
though, because I don't have the space (the CAB file for the installer could
end up being pretty large, since I only have the packager that comes with
Visual Studio which isn't near as efficient as the Wise or InstallShield
ones).  I don't think it would take a whole lot of coding, really.  I can
build something that makes use of an Access database (you don't have to have
Access on your computer to use it, the installer will load all that's
needed), that will keep all the data you enter.  If you can email me with
all the parameters you'd like it to track, and formulas it needs to use
(stargazer67 at bellsouth dot net), I'll see what I can gin up.

Oh gee, wow, if you pull this off I'd have to kiss your feet.  Lessee,
well my dream calculator would

             1) have to have a simple input for lean body mass.
Formula(s) from the lean mass calc site:

a) Body Surface Area = 0.20247 x Height(m)0.725 x Weight(kg)0.425

b) Lean Body Weight (men) = (1.10 x Weight(kg)) - 128 ( Weight2/(100 x
Height(m))2)

c) Lean Body Weight (women) = (1.07 x Weight(kg)) - 148 ( Weight2/(100 x
Height(m))2)

d) Ideal Body Weight (men) = 50 + 2.3 ( Height(in) - 60)

e) Ideal Body Weight (women) = 45.5 + 2.3 ( Height(in) - 60)

f) Body Mass Index = Weight(kg) / Height(m)2

              2) also the Katch-McArdle BMR formula:

BMR (men/women) = 370 + (21.6 X lean body mass in kg)
AND?OR
BMR (men/women) = 370 + (9.8 X lean body mass in lbs)

with descriptions of what constitutes the various levels of activity in
a side bar or something,

              3) plus the weightloss modifier for at least two groups,
and possibly three (50 or less, 100 or less, and over 100-- those who
are severely overweight can cut a lot more than a person with only 50
pounds to lose before they undercut their bmr) but that info shouldn't
be in a sidebar so the user can't pick a higher number so they can
'optimize weight loss' and end up doing themselves harm.

               4) Maybe a tie in to a simple weight chart for a nice
visual.  Input your weekly weigh-in, and it will auto re-calculate
(assuming your variables stay the same, but with the option to change
any of the variables) as you 'go down'.  This way folks won't get
confused about calorie calculators and think the total calorie
expenditure for their current weight should be what they should eat to
lose weight.

              5) Does lean body mass stay the same throughout the
weight loss phase, or is there some small amount of lean mass lost on a
lowcarb diet?  I'm sure there would be more lost on a lowfat diet if so,
so maybe there should be an indcator for whether you are doing lowcarb,
lowfat, or lowcalorie.  I don't know what the calculation would be for
the various diets.  Perhaps ask Lyle McDonald?

Basically I invision inputing one or two numbers once you've got your
variables set and each time you input a new weight it recalcs lean mass,
and calorie goals for weight loss.  Oh! and perhaps a goal input that
when reached will switch you to maintenence calories instead of weight
loss calories.

Maybe an option to input (by hand of course) fityday-type (from any
tracker proggie it doesn't really matter) numbers (protien, fat, carbs,
fiber) so you have a running daily/weekly/monthly/yearly? total of hard
numbers and percentages.  Say make it a part of the weight chart visual?

Anybody else have suggestions?

Okay, that gives me a good starting point - I can easily incorporate
suggestions as it goes along as well (we can start a new thread if we need
to for that when I get the basics done as well, since everyone might not be
drilling this far down in this one).  First thing is to get the nuts and
bolts working, then the extras after the basics are there.  Charts and
graphs shouldn't be too much of a problem, nor is importing (or exporting)
data from a spreadsheet difficult (so if you're tracking percentages in a
spreadsheet, you could auto-import that by simply telling the program where
to find your spreadsheet and the values in it - or enter by hand if you
aren't).

I'll get started today (it's raining here, so the yardwork I was planning to
do is out for now anyway), and will probably have many more questions for
you as I go along, <g>.

This doesn't take into effect the number of calories/lb that adipose
tissue uses.  The numbers look really funny without that.

I just put in 10% to 30% increases.  If you can document what to ask
for and how to adjust calories from that, I'll change it.

I figured 1 lb/week loss for every 50 lbs/week overweight, plus 0.1
lb/week extra so that it doesn't take forever to hit goal.  I put a
chart on the right side that says "weight this much... eat this
much...  to lose this much...".  Easily changed if you think other
numbers make more sense.

Some people have no clue what their activity level really amounts to.
For instance, I over estimated my activity level until I got a few
examples of activities and where they were located on the scale.  I'm
talking about the usual calculator like
http://www.exrx.net/Calculators/CalRequire.html activity scales.

I don't know.  :)  I was merely thinking along the lines of 500 cal
deficit for those with 50 pounds or less to lose, 1000 for the Centuries
and 1500 for the largest folks.

As I said, I'm no math geek. I figured Lyle would know.  Or if he didn't
he could find out who would farily easily.

You bet - I need the practice, because I'm not getting anything on the
'create' side at work at all anymore (only maintaining existing stuff, which
doesn't take a lot of time or thought).  And I'm starting to forget about
things that only come around with initial program creation, <g>.  So it's a
good skill-refresher exercise for me.

I'll continue on using what you've given me so far, unless you decide
differently.  I will ask and figure out the other currently murky things
(such as the question of LBM and how it changes) as I get to them, or maybe
someone will answer them before I get there and save me the question, <g>.
As of right now, I have the essentials of the database built and am starting
on the program itself.

$bmr = 370 + 21.6 * $lbm;

I added another 4.4*$extra_fat for now; this is kgs above ideal
weight.

I don't know what it would be, and I don't currently take it into
account.  That's why the results look strange - a 250 lb guy
(goal=160) would be eating only 1000 cals/day without that factor.

I found one web site that claims 2 kcals/lb/day.  That would add only
200 kcals to the above example, though, and makes the RMR for myself
wrong :-P  I've added that factor in.

Hmmm... maybe I'll add a slot for "if you know your current
maintenance calories, enter it here...".

Or see what the other sites do.  I did find a site that tabulated the
% ratios for various activity levels, so I've adjusted my numbers for
that for now.

That worked out to 1lb/week per 50 lbs to lose.  There's probably
limits on both extremes; 10% below maintenance for skinny folks is
Lyle's recommendation.

I'm a math geek.  That doesn't mean I know *which* math to use,
though.  If you can find trustworthy info, I can fit it into the form.

Jenny - 06 Mar 2004 18:36 GMT
I was just rereading the Pool book "Fat: Fighting the Obesity Epidemic"
which is a wonderful overview of laboratory research on diet and metabolism
up through 1998.

Pool describes in great detail some very good laboratory research that
suggests that people's metabolisms do vary hugely and that some fat people
do burn a lot less calories than people who are 80 lbs less than they do.
Even more important, added to these innate differences, once you lose 10% of
your starting weight, very good research shows that the metabolism slows
down about 15%.

So the calculators have to be taken with a huge grain of salt.

I logged my food input and exercise for slightly more than a year, measuring
portions carefully because none of the figures worked for me. I and came out
with a very consistent calorie level for losing, maintenance and another one
for weight gain.  The number I get from real experience is about 600
calories less than what the formulas (and a Medical School dietician) tell
me I should be able to eat. I am currently maintaining at exactly 10 times
my body weight in calories.

That is undoubtedly because I am way below the weight my body thinks is
normal for me (which is up around 165).

The researchers at Rockefeller University start all their weight loss
subjects with experimental levels of controlled nutrition and then slowly
bring them down until they reach the level where they lose weight. For many
of the very fat people who have failed other dieting regimens, that level
does turn out to be <gasp> 800 calories a day. Maintenance for the same
people turns out to be slightly LESS than ten times body weight before they
start to lose.

So forget the formulas unless you are Mr. or Ms. Average.

I think we all agree that YMMV when it comes to calories.  However,
many people need at least a starting point.  Plus, once you know what
the various numbers are going to be for you, there's still some math
involved if you want to fine tune everything.

Cool.  I may or may not try to make use of the Wise (not sure if sending you
all the .dll's, executable, and db would end up being any more efficient
than using the built-in packager), but I will need the host space.  I'm
still progressing on it, though it's slow going through the week (because by
the time I get home from work, I don't tend to have a lot of enthusiasm for
more coding, <g>).  So far I have the user data input screen built, and
multiple conversion functions (such as metric to standard, so the user can
use either measurement system and the program will remember which one they
prefer) built in.  I've also built in capability for more than one user to
enter/track data on the same computer, and that's about it up to now.

I do have a question for you about Wise, though - one of the components
installed with the program is the MDAC version used when building the
program (I used 2.7, which an XP user would probably already have, but a 9x
user probably wouldn't unless they have Office 2k or higher and also install
their updates regularly).  My heartburn with the V.Studio installer is that
it doesn't look to see what the user's current MDAC version is before
installing it - it just installs it every time, whether it was needed or not
(not that this hurts anything, it just wastes time and space because the
MDAC installation is the slowest part of the install as well as being one of
the larger parts of the .cab file).  Does Wise have the capability of
determining whether a component really needs to be installed before it
installs it, and if so can it store it in a separate dependency file and
only grab it as needed?

It has scripts that permit quite a latitude of queries, but I
wouldn't suggest making it that complicated since most users have
gigabyes available.  I usually use it to install Delphi applications
which have a quite small exe footprint with no dll's required, but can
query if needed.  

When you get it ready, stick all of it in a zip file and notify me
here and I'll give you a spot to send the file.

You can also include (in the zip file) an index.htm file with
download instructions for your customers.  Meanwhile I'll clean out a
spot for your page with upload instructions.

If you're using Fitday, it's known for grossly overestimating calories

This is just my opinion, but if I were you (how tall are you, BTW?)  I'd try to get that excess weight off as quickly as possible, without fasting, of course. Certainly for someone your size, 10 lbs/month isn't unreasonable, unless you have some sort of metabolic resistance to losing using this method.  When you get a little closer to normal weight, then worry about it. I doubt, personally, whether you will slow down your metabolism, but can't say that I know anything from personal experience.

In Feb., the first month I signed up for Challengers, I didn't even make 3 lbs. The other months I was doing LC, I basically shot for 10 lbs a month and usually made it. Now that I'm closer to goal, I'm readjusting my thinking so that I am not too disappointed. Also, I wasn't exercising. Now I've started and I'm seeing the weight loss starting again.

Since you have so much to lose, I'd really not worry about "slowing it down" yet.  Unless of course, you do have thyroid problems or something, in which case we should strive to help you speed it up. In that case, I'd do some research of revving up your metabolism.

If I were you, unless it quit working, I'd follow the Atkins plan...eat 2-3 meals a day, following his suggestions...see how you lose...take some vitamins.  Fat is supposed to speed up your metabolism (?) I think. If you do start slowing down towards the end, then revamp. But you've got a ways until that point, IMO.  Nothing is meant to be cruel or uncaring. Hardly. I've had some real encouragers around me keeping me going on this diet.  But, I think you are worrying a bit "prematurely."

The more overweight you are, the harder it is to do this, but it is
possible.  At 334, the "usual" recommendation is 10-12x (3340 to 4008
kcals/day), but for those with a lot to lose, it's more like 8-10x
(2672-3340) or less.  You should be losing weight at about 2 lbs/week
once you settle in to lc, although with lots to lose, more is possible
for a while.  The closer you get to goal, the slower you'll lose.

>  For example at my weight and activity level I burn an estimated

How much weight per week do you lose?  Each lb/week corresponds to a
500 kcal/day deficit; if you're losing 3 lbs/week that means you're
1500 kcals below your "maintenance" level.  Figure this out now!
Later, you can judge if your metabolism has slowed down by
re-computing this number and figuring out your new maintenance level.

Add more carbs.  IMHO this is where Atkins' CCLL comes in - it's the
right level of carbs to keep your appetite at just the right number of
calories.

If not, eat more calorie-laden foods, like fattier meats, nuts, heavy
cream, and salad dressing.

Once you know your "uncrashed" maintenance rate, you can usually fix
any crashed by eating at maintenance for 2 weeks.  After that, reduce
your calories by a few hundred cals/day for a week or two and see what
happens, then reduce again, etc, to bring you back to 1-2 lbs/week
loss.

I would modify this to be like, "At 334, the usual recommendation is more

The more overweight one is, the more of a deficit they can run without
problems.

I think the metabolism crash thingie gets too much press. :)

I agree.  Just poor wording on my part, I guess.

You'd think so, but I've got two women living in this house with
crashed metabolisms, and I can't really use the "near goal" excuse for
either.

> are you sure that they are not secretly cheating with their diet?

People keep asking me that, and no, I don't think so.  I occasionally
check their intakes carefully, and one of them rarely eats ANYTHING
much less a healthy diet.  Yesterday she got a whopping 500 calories
or so, and she was so happy she remembered to eat a lot that day!  The
other one has to force herself to eat enough, she usually stops at 800
cals or so otherwise.  She's going to try to reset her metabolism and
start LC all over again, from the beginning, with higher calories.
She *did* lose weight when she first started LC (30 lbs over three
months), but that was a year ago.

What an obnoxious malady.  You could watch what you ate religiously
and exercise like a demon every day - and then sleep-eat all the
progress away while you weren't even conscious.  It's probably quite
rare, but I can't help feeling for people who have it.  All the
willpower on earth wouldn't do you any good.  You'd have to have
someone keep custody of a key to the kitchen in order to block access
to food while you were asleep.

Over the last 14 days, I'm losing an average of 3.23 lbs per week which
equals 1,615.  Do I now add 1,615 to my average calories eaten?  which would
then work out to average overall calories burned?

Yup.  If you were eating 2,000 cals/day, you're burning 3615 cals/day.
Note that this math doesn't work right for the first two weeks
(induction) because all the water weight you lose then messes up the
numbers.

The 500 cals/lb trick makes figuring this out a lot easier.

Also note that you can figure out your multiplier now, too.  For 3615
cals/day and 334 lbs, that's 10.8 kcals/lb.  This number goes *up* as
you lose weight (more lean flesh, less fatty flesh).  You can see why
people with more to lose need to eat at 7-10x rather than 10-12x.  At
12x, you'd be gaining weight.

If you track all this on a week by week basis, you'll see the burn
rate slowly drop.  If it drops at the same rate as your weight, you're
golden.  If it suddenly seems to drop more than you expect, you're not
eating enough.  Then, eat at whatever your most recent "maintenance"
burn rate was (3615 for today, for example) for two weeks to reset
your metabolism, then try again.

As you see your burn rate drop, of course, you can lower calories
also, to keep your loss rate where you want it.
